drm/amd/pm: Use pm_display_cfg in legacy DPM (v2)

2026-03-25T10:06:00+00:00

commit 9d73b107a61b73e7101d4b728ddac3d2c77db111 upstream. This commit is necessary for DC to function well with chips that use the legacy power management code, ie. SI and KV. Communicate display information from DC to the legacy PM code. Currently DC uses pm_display_cfg to communicate power management requirements from the display code to the DPM code. However, the legacy (non-DC) code path used different fields and therefore could not take into account anything from DC. Change the legacy display code to fill the same pm_display_cfg struct as DC and use the same in the legacy DPM code. To ease review and reduce churn, this commit does not yet delete the now unneeded code, that is done in the next commit. v2: Rebase. Fix single_display in amdgpu_dpm_pick_power_state.

drm/amd: Add detailed GFXOFF stats to debugfs

2022-08-16T22:17:31+00:00

Add debugfs interface to log GFXOFF statistics: - Read amdgpu_gfxoff_count to get the total GFXOFF entry count at the time of query since system power-up - Write 1 to amdgpu_gfxoff_residency to start logging, and 0 to stop. Read it to get average GFXOFF residency % multiplied by 100 during the last logging interval. Both features are designed to be keep the values persistent between suspends.
